A bag hes 10 red marbles, 3 green marbles,
7 yelow marbles, and 5 blue merbles. What is
the probability of crowing a red marble and
then g, blue, marble without replacing the first?

Answers

Answer:

[tex]\frac{3}{5}[/tex]

Step-by-step explanation:

Probability is the chance of an event happening. One finds the probability of an event by using the following general formula,

[tex]\frac{desired}{total}[/tex]

In this case, the desired outcome is pulling whether a red or blue marble from the bag, the desired equals the sum of the number of red and blue marbles.

(red) + (blue)

= 10 + 5

= 15

The total number of marbles is the sum of all the number of marbles in the bag.

(red) + green)  + (yellow) + (blue)

= 10 + 3 + 7 + 5

= 25

Now substitute these values into the formula to find the probability, then simplify,

[tex]\frac{15}{25}[/tex]

Divide both the numerator and denominator by (5),

[tex]\frac{3}{5}[/tex]

Terry finished cooking at 7:36 p.m. She cooked for 2 hours and 40 minutes. What time did she start cooking?​

Answers

Answer:

2:56 pm

Step-by-step explanation:

end time: 7:36 pm

Borrow one hour from the hours and add it as 60 minutes to the minutes.

7:36 pm = 6:96 pm

Now subtract 2:40 from 6:96.

Subtract 2 from 7 and subtract 40 from 96.

What is the range of possible sizes for side x?

Answers

Answer:

x = 3.96

Step-by-step explanation:

To find the missing side length you'll need the formula a^2 + b^2 = c^2

a and b would be the shorter ends, 2.8 and 2.8

c would be the longer end that's opposite the right angle.

so substitute values

2.8^2 + 2.8^2 = c^2

7.84 + 7.84 = c^2

15.68 = c^2

√15.68 = √c^2

3.959797 = c

c = 3.96

side c would be side x so x is 3.96

Chau rented a truck for one day. There was a base fee of $18.95, and there was an additional charge of 95 cents for each mile driven. Chau had to pay $198.50
when he returned the truck. For how many miles did he drive the truck?

Answers

Let's say John drove 2 miles. He had to pay the base fee of $18.99 and $.75(2) = $1.50, so he paid $20.49 total.

We are given his total, though, and asked to find the mileage.

18.99 + .75m = 199.74

-18.99 -18.99

.75m = 180.75

.75 .75

m = 241

So, John drove 241 miles.

If I had 36 apples what is the percentage of 20

Answers

Answer:

20 apples is 55.55% of 36 apples.

Step-by-step explanation:

Given that I had 36 apples, to determine what is the percentage of 20 of them, the following calculation must be performed:

36 = 100

20 = X

(20 x 100) / 36 = X

2000/36 = X

55.55 = X

Therefore, 20 apples is 55.55% of 36 apples.

No, the claim that the three samples are from populations with the same mean is not correct and this can be determined by using the given data.

Given :

The Hypothesis test is given below:

Null Hypothesis: [tex]H_0:\mu_1=\mu_2=\mu_3[/tex]

Alternative Hypothesis: [tex]H_a:\mu_1\neq \mu_2\neq \mu_3[/tex]

For the F-test, the test statistics is given by:

[tex]F = \dfrac{MS_{\rm{between}}}{MS_{\rm{within}}}[/tex]

Now, substitute the values of known terms in the above expression.

[tex]F = \dfrac{15.8252}{0.6896}[/tex]

[tex]F = 22.95[/tex]

So, the p-value regarding the value of F is:

x = 19 yards = 57 feet
The ball is 57 feet from the hole.

Explanation:
The distance from the tee to the hole is 181 yards.

Using the Pythagoras Theorem,
x^2 + 180^2 = 181^2
x^2 + 32400 = 32761
x^2 = 361
x = sqrt(361)
x = 19 yards

1 yard = 3 feet
x = 19 yards = 57 feet

B Reading Choose the best estimate for the multiplication problem below. 85 x 86
A. 8100
B. 10,400
C. 12,200​

Answers

Answer:

A. 8100

Step-by-step explanation:

85 x 86

To estimate, we multiply 85*100, which is the easiest multiplication, as a multiplication by 100 is the same as placing two zeros at the end of the number.

85*100 = 8500

Since 86 < 100, 85*86 < 8500. Thus, the correct estimate is given by option A.

Suppose that you are interested in the relationship between the return rate on a stock in 2010 compared to the return rate in 2009.-You believe that the return rates in both years are positively correlated. A sample of 15 stocks'yields the following regression results: b0=5.3, b1= 1.04, sb= 1.79, and MSE = 35.4. 1:79, sb= 0.2163, R2 = 0.64

iii. What is the predicted value of y when x = 5
iv. Calculate the error sum of squares.
v. Calculate the total sum of squares.
vi. Calculate the regression sum of squares.
vii. Prepare the analysis of variance table for regression.

Answers

Step-by-step explanation:

1. we have b1 = 1.04 which is positive. we say that the return I. 2009 is positively correlated with the return in 2010.

2. Y = b0 + b1X

Y = 5.3 + 1.04X

3. If x = 5

Y = 5.3 + 1.04(5)

Y = 10.5

4. SSE = mse x (n-2)

n = 15, mse = 35.4

SSE = 35.4 x(15-2)

= 35.4 x 13

= 460.2

5. We are to find SST here

R² = SSR/ SSR + SSE

R² = 0.64

SSE = 460.2

0.64 = SSR/SSR+460.2

Cross multiply

0.64(SSR + 460.2) = SSR

0.64ssr + 294.528 = SSR

Collect like terms

294.528 = SSR - 0.64SSR

294.528 = 0.36SSR

SSR = 294.528/0.36

SSR = 818.13

SST = SSR + SSE

= 818.13 + 460.2

= 1276.53

6. The SSR has been calculated to be 818.13

From the three windows, through the cracks of the old wooden shutters, came only a few scattered sunbeams which, in the midst of the obscurity, made a soft brightness that bathed surrounding objects in a diffused and tender light. It was cool here in comparison with the overpowering heat that was felt outside, under the fierce rays of the sun that blazed upon the front of the house.Standing before the press which faced the windows, Dr. Pascal was looking for a paper that he had come in search of. With doors wide open, this immense press of carved oak, adorned with strong and handsome mountings of metal, dating from the last century, displayed within its capacious depths an extraordinary collection of papers and manuscripts of all sorts, piled up in confusion and filling every shelf to overflowing. For more than thirty years the doctor had thrown into it every page he wrote, from brief notes to the complete texts of his great works on heredity. Thus it was that his searches here were not always easy.
